<P>PROBLEM TO BE SOLVED: To provide a cooling system for a power converter capable of conserving energy and reducing noises in the cooling system cooling the power converter. <P>SOLUTION: The cooling system for the power converter includes an arithmetic operation arithmetically operating a calorific prediction value of a semiconductor device used for the power converter, a cooler cooling the semiconductor device, and a cooler controller controlling the cooler. The cooler controller improves the cooling capacity of the cooler in case of a high calorific prediction value so that the temperature of the semiconductor device does not exceed a fixed value, and conducts control reducing the cooling capacity in case of a low calorific prediction value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
